Mechanical Multimeter
The appearance of the mechanical multimeter is different from that of the digital meter, but the shift knobs of the two are similar, and the gears are basically the same.
On the mechanical watch, you will see a dial as shown, with eight scales on the dial:
The scale marked with "Ω" is used for measuring resistance.
Marked with "~" is the scale used to measure AC and DC voltage and DC current.
The one marked with "HFE" is the scale used to measure the triode.
Marked with "LI" is a scale for measuring the current and voltage of the load.
Marked with "DB" is the scale that measures the level.
